ΓòÉΓòÉΓòÉ 1. introduction to snapshot V2 ΓòÉΓòÉΓòÉ
snapshot V2 is a 32-bit screencapture utility for the OS/2 presentation
manager. snapshot V2 enables You to save any arbitrary rectangle of the screen
in a graphic data file.
snapshot V2 supports as graphic file formats the OS/2 bitmap format (bmp) and
the tagged image file format (tif).
snapshot V2 takes the extension of the filename to determine, which graphic
format to generate. The colordepth of the generated image is depending on the
actual graphic hardware and the file format specifications. snapshot V2 chooses
the optimal colordepth automatically to generate the best possible results.
ΓòÉΓòÉΓòÉ 2. the menu bar ΓòÉΓòÉΓòÉ
The following menus could be activated either by using the menu bar or by
pressing the specified key combination:
menu key combination
File <alt f>
Trackframe <alt t>
Magnify <alt m>
Options <alt o>
Help <alt h>
ΓòÉΓòÉΓòÉ 2.1. File ΓòÉΓòÉΓòÉ
The menu File contains the three menuitems save, save as, and quit.
The menuitems save and save as will be disabled until You have successfully
taken a picture; that means until You have choosen a rectangle of the screen,
that should be saved, and afterwards pressed the Return key.
If You choose save the image will be saved with the filename specified in the
entry field. This gives You the opportunity to save a taken image in another
file format by a quick change of the filename extension.
Choosing save as brings up the well known file saving dialog, which might be
useful if You have to search for the location where You want the file to be
placed.
To exit snapshot V2 You choose the menuitem quit or press the F3 key.
ΓòÉΓòÉΓòÉ 2.2. Trackframe ΓòÉΓòÉΓòÉ
Selecting Trackframe at the menu bar (or pressing <alt t>) does not bring up
the usual drop down menu but starts the tracking process. That gives You the
possibility to choose which rectangle of the screen is to be captured.
ΓòÉΓòÉΓòÉ 2.3. Magnify ΓòÉΓòÉΓòÉ
snapshot V2 allows You to observe the area around the pointer magnified.
Magnification is toggled by selecting Magnify at the menu bar or by pressing
<alt m>.
ΓòÉΓòÉΓòÉ 2.4. Options ΓòÉΓòÉΓòÉ
The menu Options contains the three menuitems set font, reset font, and beep.
Selecting the menuitem beep toggles an acoustic signal, which is generated when
a capture of the screen is actually taken.
The font You have chosen, the position of the snapshot V2 application window,
and if the beep is activated are settings that will be saved, if You have
started snapshot V2 from a hard disk - it does not seem to make any sense if
You have startet the application from a CD-ROM.
ΓòÉΓòÉΓòÉ 2.5. Help ΓòÉΓòÉΓòÉ
Additional to the usual menuitems in the Help menu there is an item called
manual, which provides a direct access to the snapshot V2 online reference.

ΓòÉΓòÉΓòÉ 4. using the mouse ΓòÉΓòÉΓòÉ
Differently from most other applications snapshot V2 uses all three
mousebuttons. This gives You the possibility to do all necessary work while
positioning the trackframe with one hand.
If Your mouse has only two buttons, pressing mousebutton three is simulated by
pressing mousebutton two while holding down the alt-key.
ΓòÉΓòÉΓòÉ 4.1. mousebutton one ΓòÉΓòÉΓòÉ
mousebutton one is used for managing the tracking. Moving the mouse while
mousebutton one is pressed varies the size of the tracking frame. Releasing
mousebutton one after tracking leaves the trackframe on the screen ready for
being modified via keyboard or ready for taking a capture.
A doubleclick on mousebutton one cancels all tracking and makes the snapshot V2
application window reappear.
ΓòÉΓòÉΓòÉ 4.2. mousebutton two ΓòÉΓòÉΓòÉ
mousebutton two toggles the snapshot V2 information window while tracking.
The snapshot V2 information window provides information like position and size
of the trackframe and contains the magnifying glass, in which the area around
the pointer can be observed.
ΓòÉΓòÉΓòÉ 4.3. mousebutton three ΓòÉΓòÉΓòÉ
mousebutton three (or <alt mousebutton two>) toggles magnification while
tracking.
ΓòÉΓòÉΓòÉ 5. some hints ΓòÉΓòÉΓòÉ
Choose the right colordepth for Your display
If You are using a display width a high color resolution (16 bit or higher) but
want to take an image with only 256 colors, reduce the color resolution of the
display. This gives in most cases better results than converting a highcolor
(or truecolor) image to a 256 color image by software. In addition You will
save a lot of hard disk capacity.
It is possible to move the origin
Sometimes You may want to have another origin than the usual one at the lower
left corner of the screen. This is especially useful if You want to take the
same part of a picture several times.
To change the origin move the pointer to the field width the origin coordinates
in the snapshot V2 window before You start tracking. If You click mousebutton
one within the field (You will know, if You are inside the field) the origin is
going to move. Clicking mousebutton one again sets the origin to the
screenposition You choose. All position information is now relative to the new
origin.
To reset the origin to the lower left corner of the screen move the pointer
back to the field width the origin coordinates and click mousebutton one.
